Embodiment 1

[0042]Mix 10 parts of fish meal, 16 parts of animal feed (including 12 parts of meat and bone meal, 4 parts of animal offal powder), 60 parts of vegetable feed (including 14 parts of flour, 18 parts of soybean meal, 16 parts of rapeseed meal, 8 parts of cotton meal, peanut 4 parts of meal), 9.5 parts of oil, 1 part of multivitamin, 2 parts of compound mineral, 0.5 part of bile acid; 1 part of other ingredients (including 0.3 part of adhesive, 0.5 part of digestive enzyme, 0.2 part of food attractant), stir and mix well , after pelleting, to obtain feed for the prevention of hepatobiliary syndrome in herbivorous fish.

[0043] Take grass carp as a test example, use the above-mentioned feed for 1-2 days every 7-10 days, and the feeding amount should be full; strengthen artificial oxygenation during the prevention period to ensure that the dissolved oxygen at the bottom of the pond is at 4.5mg / L or above.

[0044] Effect: no hepatobiliary syndrome, grass carp has good body shap...

Embodiment 2

[0046] 40 parts of fish meal, 18 parts of animal feed (including 15 parts of meat and bone meal, 3 parts of animal viscera powder), 26 parts of plant feed (including 16 parts of flour, 6 parts of soybean meal, 4 parts of rapeseed meal), 11.2 parts of oil, compound 1 part of vitamins, 2 parts of compound minerals, 0.8 parts of bile acid; 1 part of other ingredients (including 0.3 parts of binder, 0.5 parts of digestive enzymes, and 0.2 parts of food attractant), stirred and mixed, obtained after granulation for the treatment of carnivorous Feeds for hepatobiliary syndrome in fish.

[0047] Take California perch as a test case, use it continuously for more than 1 week or until it is cured, the feeding amount should be full; during the treatment period, artificial oxygenation should be strengthened to ensure that the dissolved oxygen at the bottom of the pool is above 4.5mg / L throughout the day (including night) .

[0048] Effect: It can effectively cure California perch hepatob...

Embodiment 3

[0050] 25 parts of fish meal, 20 parts of animal feed (including 12 parts of meat and bone meal, 8 parts of animal offal meal), 41 parts of vegetable feed (including 12 parts of tapioca starch, 16 parts of soybean meal, 8 parts of rapeseed meal, and 5 parts of cotton meal) , 9.5 parts of oil, 1 part of multivitamin, 2 parts of compound mineral, 0.5 part of bile acid; 1 part of other ingredients (including 0.3 part of adhesive, 0.5 part of digestive enzyme, 0.2 part of food attractant), stir and mix well, after granulation , to obtain feed for the prevention and treatment of fish hepatobiliary syndrome.

[0051] Taking herring as a test case, it was found that herring suffered from severe hepatobiliary syndrome and had a high mortality rate out of water before fishing started in winter. Change to this feed, and the amount of feeding should be satiated; artificial oxygenation should be strengthened during the period to ensure that the dissolved oxygen at the bottom of the pool i...

Abstract

The invention discloses a feed for preventing and treating liver and gallbladder syndromes of fish. The feed comprises the following components in parts by weight: 10-40 parts of fish meal, 10-20 parts of an animal feed except the fish meal, 25-60 parts of a plant feed except bran, 4-15 parts of fat, 0.2-1 part of complex vitamins, 2-5 parts of composite mineral substances, and 0.5-1 part of taurine or cholesterol, or 0.2-0.8 part of bile acid, or 0.5-1 part of a mixture of taurine, cholesterol and bile acid. According to the feed disclosed by the invention, the proportion of animal feed raw materials is increased, the proportion of plant feed raw materials is controlled, particularly the dosage of raw materials rich in soluble non-starch polysaccharides needs to be controlled, and the bile acid, the taurine and the cholesterol are complemented, so that the reabsorption quantity of bile acid and raw materials thereof can be increased, the liver is restrained from starting a signal channel for synthetizing the bile acid, fat absorption is facilitated, and the feed has favorable effects of preventing and treating the liver and gallbladder syndromes of the fish including crucian carps, grass carps, perches, black carps, parabramis pekinensis and the like.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to a feed for preventing and treating fish hepatobiliary syndrome. Background technique [0002] Fish hepatobiliary syndrome is a common disease in the past ten years. It is one of the fish diseases that frequently occur in my country. The epidemic season is mainly from June to October. Herring, tilapia, etc., both fingerlings and adults can occur, and the mortality rate can be as high as 50%-90%, resulting in heavy losses. [0003] In the early stage of fish hepatobiliary syndrome, there are no obvious symptoms on the outside. After dissection, the liver is obviously enlarged. Some liver parts or most of the liver become "green liver". Alternate "flower liver" symptoms, light touch is fragile, the gallbladder is obviously enlarged, the color of the bile turns yellow and white until it is colorless, and in severe cases, the gallbladder is congested and red, and the bile also turns red. Due...
